Note 96 — Chapter XXVIII · THE DISCOVERY OF THE EINSTEINIAN LAW OF GRAVITATION

In point of fact, it was when Einstein applied the principle of Action (to be discussed presently) that he first recognised the error in his original law. Also we may note that the law of curvature , when it does not reduce to , represents a non-homogeneous type of curvature, and most certainly not a homogeneous spherical curvature as certain lay writers have stated, drawing hasty philosophical conclusions therefrom.
